ODBC SQLBindParameter for numeric

Erwin Brandenberger

How should be the content of SQL_NUMERIC_STRUCT when writing to DB ?

 

I used the same as reading, but it will not work.

 

Sample: 0.200000 [for decimal(9, 6) as dbcolumn]

 

{precision=6 '\x6' scale=6 '\x6' sign=1 '\x1' ...}

6 '\x6'

6 '\x6'

1 '\x1'

0x000000cfae63cbfb "@\r\x3"

64 '@'

13 '\r'

3 '\x3'

0 '\0'

...

 

ret = SQLBindParameter(hstmt, idx, param, SQL_C_NUMERIC, SQL_NUMERIC, numeric.GetPrecision(), numeric.GetScale(), numeric.GetAsNumericStruct(), 0, data->GetResultLength64());

 

What is wrong with this call ?

 

Reading works, writing not !
